Problems solved by technology

The oil storage cotton used in electronic cigarettes has the following disadvantages: First, the material of the oil storage cotton is generally made of PET fiber or foam sponge, which only has a simple oil storage capacity, and the oil storage capacity is low
Second, man-made fiber PET and foam sponge degrade for a long time, and are prone to produce toxic and harmful substances during the degradation process, thereby polluting the environment; with the promulgation and promotion of the national ban on plastics, these materials will gradually be replaced
Third, studies have shown that PET materials and foamed sponges will have a burnt smell when heated at high temperatures, and will also produce harmful substances, which will cause harm to the body
Fourth, when using the existing e-cigarettes, since the oil tank cannot be sealed, there will be oil leakage and oil spills during use
Fifth, since the oil storage cotton and the e-juice bin need to be closely assembled, its diameter is slightly larger than the inner diameter of the e-juice bin, which makes the operation inconvenient and the assembly process takes a long time, which affects production efficiency

Abstract

The invention discloses a biodegradable polysaccharide aerogel oil storage material and a preparation method thereof. The oil storage material comprises an outermost paper tube layer, a middle plant polysaccharide aerogel oil storage cotton layer and an inner through core hole. The oil storage cotton layer is prepared from the following raw materials: konjac glucomannan, agar, Arabic gum, food-grade wax, starch and glycerol. The prepared biodegradable plant polysaccharide oil storage cotton has the characteristics of rich net structures, high specific surface area, large porosity, small density and the like, and can adsorb more tobacco tar, so that the oil storage rate of the oil storage material is improved; and on the other hand, the oil storage material has excellent water resistance and tobacco tar erosion resistance, can keep a complete form in water or tobacco tar for a long time, and has good elasticity. Furthermore, the raw materials are natural plant polysaccharides, so that the degradation speed is high, white pollution is not caused, toxic and harmful substances are avoided, and harm to human health is avoided.

Description

technical field [0001] The invention belongs to the technical field of environmental protection materials, and in particular relates to a novel biodegradable plant polysaccharide airgel oil storage material and a preparation method thereof. Background technique [0002] At present, with the improvement of the quality of life and the continuous improvement of people's health awareness, the harm of traditional tobacco products is gradually becoming known to people, and many people turn to new electronic cigarette products. Electronic cigarettes are generally composed of battery components, suction nozzles and atomizers. The atomizer includes oil storage cotton and heating components. When heated, the smoke oil in the oil storage cotton is atomized to generate smoke. In this way, the user has a feeling similar to smoking when smoking, because the electronic cigarette does not produce harmful substances such as tar, and the atomized smoke is quickly diluted in the air, which wil...
